This might be better placed in the luthier's corner, so if it needs to be moved, moderators, please do so. My 2000 Modulus Flea 4 is suffering from a bit of A string buzz. I've traced the problem to the nut, and its simply a result of not having enough downward pressure as the string "breaks" across the nut. I've had this problem on other basses before, and have always remedied the problem by simply adding a string tree for the A string. However, those were all basses that had wooden headstocks. So my question is this: Is there anything I should know about attaching a string tree to the headstock of my carbon fiber necked Modulus Flea bass? Typically I've just drilled a small pilot hole and then attached the string tree.... pretty simple stuff... but carbon fiber is a whole new world to me. Thanks in advance for any help that can be offered.
